Framework Migration Recommendation for Office Add-ins

[chetankotwal]

Hi Team,

I currently have Excel, Word, and PowerPoint add-ins built using pure JavaScript and a .NET Core API for the backend. I’m looking to migrate my add-ins to a framework, and after reading various articles, I’m confused about whether to use React or Blazor.

Could you please advise on which framework would be better for my situation? I've seen some articles suggesting that using Blazor would still require reliance on JavaScript for Office.js integration.

Given that my add-in is large and complex, with collaborative features for multiple users, I am particularly focused on scalability, fast development, and reduced code complexity.

Also suggest is other framework if it is there!!!!

Thank you!
